Commercial panels, service and distribution
The gear that feeds a Sacramento building. Replacement, capacity, subpanels, feeders, disconnects, and three-phase distribution — separated before anyone quotes a swap.
Commercial panel replacement, service upgrades, and distribution
The gear that feeds a Sacramento building. Replacement, capacity, subpanels, feeders, disconnects, and three-phase distribution — separated before anyone quotes a swap.
Commercial panel replacement
The equipment is damaged, obsolete, or no longer addable. That is replacement of the gear — not automatically more amps.
Panel replacementCommercial service upgrade
The building needs more capacity after the load calculation says the existing service is short. A service upgrade is not a default to more amps.
Service upgradeCommercial subpanel
The utility service still has headroom. Subpanels, feeders, disconnects, and meter banks move distribution to where the load actually lives.

How commercial panel work is separated from a service increase
On occupied property, replacement, capacity, and distribution are different shutdowns. They get named before anyone quotes a swap.
-
Condition vs capacity
Damaged, obsolete, or no-longer-addable gear is replacement of the can — not automatically more amps. A building that needs more capacity after the load calculation is a service upgrade.
-
The shutdown is the schedule
You provide the new gear; the utility schedules the disconnect. Occupied floors, tenants, and after-hours access decide the window as much as the conductors do.
-
Subpanels vs the utility
If the service still has headroom, subpanels, feeders, and disconnects move distribution to where the load lives. That does not involve a service increase.
-
Meter banks are the utility interface
Sockets, layout, and a bank the utility will still accept are a different job from a building service increase. Crossing those without saying so is how a quote misses the shutdown.
Commercial panel and distribution services
- Commercial feedersFeeders sized to the load and the distance — not to whatever conduit is already in the rack.View service
- Commercial disconnectsA disconnect in sight of the equipment, rated for the load, so the unit can be serviced without killing the floor.View service
- TransformersDry-type transformers placed, fed, and grounded so the secondary is a usable voltage for the equipment that needs it.View service
- Three-phase distributionThree-phase distribution that matches the machines on the floor — not a single-phase workaround.View service
- Meter banksMeter banks replaced or reworked so each unit is metered cleanly — and so the utility can actually read them.View service
- Multifamily service upgradeThe building service increased after the load is established — house meters, unit loads, and the utility on one schedule.View service
What building distribution connects to

Commercial panel questions
What property managers ask before a shutdown is scheduled.
Can you replace a panel without increasing the service?
Yes. Same-size replacement is the usual job when the can is the problem. A commercial service upgrade is only after the load has been shown to need it.
Does the building have to go dark?
The service cannot be swapped live. How long depends on whether the utility has to disconnect, and you get the window before the day. Occupied floors are staged around that.
Is a subpanel cheaper than a service upgrade?
It is a smaller job when the service has headroom. If the building is already short, more spaces do not help. That number comes from the calculation, not from the quote.
What do you need from us?
A photo of the gear with the doors open, what cannot stop, and who has to sign off. Nameplates and a floor plan help when distribution is moving.
What are the standard sizes of commercial electrical panels?
Common mains are 100, 200, 400, and up. The load calculation and the utility service determine the required size.
